ZXing-C++ is an open-source, multi-format 1D/2D barcode image processing library written in pure C++20, ported from the Java ZXing library with improved runtime and detection performance. It reads and writes many barcode symbologies (QR Code, Data Matrix, Aztec, PDF417, EAN/UPC, Code128, etc.) and offers bindings for many languages and platforms.

Use cases

• decode qr codes from images in c++
• read barcodes from camera frames in an android app
• generate qr code images from text
• scan data matrix codes on shipping labels
• add barcode scanning to a python application
• detect pdf417 codes from scanned documents

When to choose

• you need fast, dependency-free barcode reading/writing in C++ or via native bindings
• you need broad symbology support including QR, Data Matrix, Aztec, and PDF417
• you need thread-safe barcode processing in a production application

When to avoid

• you need a ready-made GUI scanning app rather than a library
• you only target Java/JVM and can use the original ZXing directly
• you need symbologies not listed as supported, such as certain niche legacy formats
